CF543-dUTP can be used for TUNEL assay, or to synthesize labeled DNA probes for in situ hybridization and nucleic acid blotting applications. CF543 is an orange fluorescent dye with an excitation spectrum optimally matching the 543 laser line. Antibody conjugates of the dye are much brighter than those of Alexa Fluor? 546.
